I am a big fan of Wood
Epoxy Saturation Technique (Fondly refered to as the WEST System. In theory, it produces boats that are some of the strongest and stiffest for their weight. Pound for pound, properly engineered and constructed, WEST System is actually stronger and stiffer than steel. BUT the caviat of 'properly engineered and constructed' is a big one.
Maintenance is about like a fiberglass boat except that you don't have worry about blisters and in theory you don't have to worry about deck coring problems.
I have seen a number of 13 to 20 (or more) year old WEST System boats and have actually gone to survey on one. Most have held up extremely well. Which brings me to the one that I actually went to survey on. This was a 18 year old Farr 38 that had been raced very hard, was of dubious build quality, and which may have had a very hard grounding.
In any event, there appeared to be significant delamination of the planking in the area on either side of the keel. The surveyor and I concluded that it would have been a difficult repair requiring the boat to have been thoroughly dried out and then the veneers reattached some how.
A couple things that were significant and in WEST Systems favor was that there was no signs of rot even though this was in a damp area near the keel. Also even with the delamination, there were no obvious signs of flexure or leaking.
I did not proceed with the purchase of that boat and the owner apparently was able to make the repairs in a comparatively short period of time selling the boat with a survey that no longer found signs of delamination.
I looked at a WEST System built Farr 1104 that was actually a little older and had similar hard use but which was completely sound.
I would like to echo what Sailor Mitch said about MAS. I also prefer MAS
Epoxy to WEST because of the lack of amine blush and reduced alergens.
